Such interfaces might be closer than you think. An interface that stimulated the processing layer that detects complete objects (e.g. bananas) was used in a research setting to provide vision to blind people: https://en.wikipedia.org/wiki/Visual_prosthesis#Dobelle_Eye https://en.wikipedia.org/wiki/Visual_prosthesis#Dobelle_Eye It had bad resolution, required those people to learn how to see using it, and had biological problems (wires exiting the skull); all these do not seem to be fundamental problems, but ones that require incremental development.
